Hi there:

It’s very possible that during your intake manifold swap out that the crankshaft position sensor may have been damaged or incorrectly reinstalled; as I believe that needs to be removed in order to replace the intake manifold on your Town Car. There are about two dozen or so mechanical or electrical parts that all contribute to the starting process of any vehicle, so you might want to have a professional mobile mechanic complete a car is hard to start inspection first; so they can pinpoint the source of the issue and recommend the right repairs be completed.

Hi there. From the description you provided, using starting fluid and the engine starting, leads me to believe no fuel is present. Assuming, the fuel pressure test is accurate and within specification, leads me to believe there is no injector signal. This may be the result of a blown PCM fuse. If power is present at the fuel injector connector, installing a noid light into the injector connector and cranking the engine is the next step. The noid light should flash as the engine cranks. If this does not happen, look for a loose ground wire, that may have been inadvertently left disconnected. I recommend having your vehicle’s no start be diagnosed and repaired by a certified technician, such as one from YourMechanic.
